Hi all,
Information on this might be burried into the archives, but after a little searching; I could not really find it. I am currently using LE85 with standard (old) Ti diaphragm but need to buy replacements as one of the diaphragm is slightly damaged and slightly less efficient. I fancy trying the al diaphragm of the 2421, as it seems that they are so much sweeter.

Question is, I use these in a 2 ways set up, could switching to the Al membranes reduce HF extension in any way? It seems like most posts I seen used these in combination with an extra tweet. I'd like to keep it simple for the time being as the HF is satisfactory to my ears...

Thanks for your help,
